Thank you Jibbybagger, I went back and had a look and I found the post I was referring to and yes it was callsign30 and I also had a look at the suggested timeline from callsign30 and I thought it was worth commenting on because the Bollsta is still showing as available come June (accepting Melandix71 comment that its a cone of silence around rig bookings until the client publicly announces the booking). So we have the last of the 3D being delivered in March (confirmed) then possibly the farm in announcement by Woodside in April and then in May the big Africa Energy Conference (confirmed) that Woodside are sponsoring (why do that if you are not a major player in the region???) and then in June the Bollsta apparently becomes available. It does look viable but what other possible indicators should we be looking for to confirm this timeline, for example Vesna popping the cork on a bottle of 2013 Taste of Diamonds Champagne or Ernie placing an order for a box of Gurkha Royal Courtesan Cigars or Iain booking the VVIP private room at the Spearmint Rhino in Vegas ?
